Title: Effects of clozapine and other dibenzo-epines on central dopaminergic and cholinergic systems. Structure-activity relationships. Author: Bürki HR, Sayers AC, Ruch W, Asper H. Journal: Arzneimittelforschung; 1977; 27(8):1561-5. PubMed ID: 20900. Abstract: Structure-activity relationships of 16 dibenzoepines, including clozapine, loxapine, clothiapine and perlapine, have been investigated with regard to locomotor inhibition, cataleptogenesis, apomorphine antagonism, arousal inhibition, effect on striatal dopamine metabolism, and in vivo and in vitro anticholinergic potency. Thioridazine and the classical neuroleptics haloperidol and chlorpromazine were included in the study for comparison. The classical tests used to detect neuroleptic activity in laboratory animals were found to be poor predictors of possible clinical effectiveness of the dibenzo-epines.[Abstract] [Full Text] [Related] [New Search]
